commit 502f75514737f598d1b2134091b364f425bee703 Author: Wei Liu <wei.liu2@xxxxxxxxxx> AuthorDate: Fri Aug 17 16:12:22 2018 +0100 Commit: Wei Liu <wei.liu2@xxxxxxxxxx> CommitDate: Tue Aug 21 14:57:31 2018 +0100 x86/mm: don't reference hvm_funcs directly It is generally not a good idea to reference the internal data structure of the another subsystem directly. Introduce a wrapper function for the invlpg hook. No functional change.
